The machine has four fans [A] [B] [E] [F] to ventilate the interior of the machine. There is a
temperature/humidity sensor (S18)[D] at the front (lower right) of the machine. The machine
takes in air from the left of the machine and exhausts it from the right of the machine after it
cools the machine interior.
The ozone filter [C] is installed at the right of the fusing unit cooling fan (FAN1), which helps
make it easier to replace the filter.
